Recombinant human Transferrin-APO is expressed in CHO cells to ensure proper folding and authentic mammalian post-translational modifications. This tag-free protein retains the native structure and high bioactivity of human transferrin in its iron-free (apo) form, making it suitable for diverse applications in cell culture and iron metabolism research.

Transferrin-APO is the iron-free form of transferrin, a glycoprotein essential for iron transport and regulation. It binds iron ions with high affinity to deliver them to cells via transferrin receptors, playing a crucial role in iron homeostasis and cellular uptake. Recombinant human Transferrin-APO is widely used in cell culture supplementation, studies of iron metabolism, and biopharmaceutical development.
